1 Scope
This International Standard specifies the graphical symbols and colours used to identify, on road vehicles, the correct type of fluid to be used for:
-
a) petroleum-base brake fluid systems;
-
b) non-petroleum-base brake fluid systems.
NOTE 1 Should future technical development add further classifications of fluids, new additional symbols will be designated.
NOTE 2 The same symbols are also used for labelling the fluid containers (see ISO 3871).
